Great advice has already been given.

Two things I would do first.

1. Install a fuel pressure gauge on the front of the fuel rail. That way if it won't start you will know for sure if you have fuel pressure or not. If you do you can eliminate the fuel pump and the rest of the fuel system and the electrics required to make the pump run.

2. Get in the habit of checking the battery voltage before starting the car. Could be battery or charging system problem and it's possible that the battery isn't quite providing enough juice to start. You may be able to determine that if the battery voltage is 12.5 the car will start but if it's 12.3 the car will crank but not well enough to start. It's unlikely but you've already looked at some of the likely stuff.

Also clean the electrical connection to the AFM. I found mine was pretty bad. I wouldn't think this would cause the starting problem but it couldn't hurt.

Let us know when you find it.
